The TLV1012 has no VCC pin, the output and VCC are the same pin. This is ideal for a two wire microphone cable.

However, it can be used outside a microphone to amplify audio signals.

We're using the TLV 1012 as a pre amplifier for our MIC input. We're facing a specific noise coupled to Pre amplifier output whenever Wi-fi enabled. In data sheet , it has suggested to connect 10pf & 33pf on Pre amplifier o/p for avoiding noise due to GSM signal (980, 1800/1900 MHz). Similarly can i use some capacitor to avoid Wi-fi specific noise (2400 MHz)? what should be the capacitor value? can you please guide me on this issue?
